Abstract: A structured packing having a surface area density in the range of about 500 m2/m3 to about 675 m2/m3 includes a plurality of corrugated plates disposed in vertically parallel relation. Each plate has at least one aperture and a plurality of regularly spaced and substantially parallel corrugations disposed in crisscrossing retation to the corrugations of an adjacent plate. The apertures have an equivalent diameter of less than about 4 millimeters but greater than about: 2 millimeters. The corrugations have a corrugation angle (~) relative to horizontal in the range of about 40° to about 60°. Each corrugation, when approximated to be substantially a triangular cross-section, has an included angle (.beta.) defined by two sides of the corrugation in the range of about 90° to about 100°. The structured packing is used in exchange columns for exchanging heat and/or mass between a first phase and a second phase in processes such as cryogenic air separation.

Title: Protein having pdz domain sequence
Inventor: FUNAHASHI SHIN-ICHI
IPC: C12N1/21
Filed: 1998-08-12
Abstract: In the process of analyzing changes in gene expression by TNF.alpha. in human umbilical vascular endothelial cells, a gene showing enhanced expression due to the stimulation with TNF.alpha. was isolated. As the result of screening with the use of this gene as a probe, a gene encoding a novel protein was isolated. By analyzing the protein encoded by the thus isolated gene, it has been found out that this protein is a novel one which has never been reported hitherto and has a PDZ domain in its molecule playing an important role in protein/protein interactions.

Title: Low profile catheter valve and inflation adaptor
Inventor: BLEAM JEFFEREY C
IPC: A61M29/02
Filed: 1998-11-20
Abstract: A low profile catheter valve comprising a movable sealer portion (30) is positioned within the inflation lumen (40) of a catheter. The sealer portion (30) forms a fluid tight seal with the inflation lumen (40) by firmly contacting the entire circumference of a section of the inflation lumen (40).  The sealer portion (30) may be positioned proximally of a side-access inflation port (22) on the catheter, to extablish an unrestricted fluid pathway between the inflation port (22) and an inflatable balloon (20) on the distal end of the catheter. As desired, the clinician may move the sealer portion (30) to a position distal of the inflation port (22), thereby preventing any fluid from being introduced into or withdrawn from the balloon (2) via the inflation port (22). An inflation adaptor (200) moves the sealer portion (30) within the catheter to establish or close the fluid pathway between the inflation port (22) and the inflatable balloon (20). In use, the catheter is placed into the adaptor (200) with the sealer portion (30) to a second position which allows passage of fluid into the inflation lumen (40).  An actuator (220) on the adaptor (200) is used to drive the sealer portion (30) to a second position which allows passage of fluid into the inflation lumen (40). The balloon (20) is then inflated and the actuator (220) is used to move the sealer portion (30) to again block the inflation lumen (40). The adaptor (200) is configured to allow the sealer portion (30) to be driven to a third position which is further from the inflation port (22) than the first position.
